Kindof 20/20 hindsight to do it now, but it might give you some idea of the car's history and mileage.
I kindof doubt that the cluster was switched to falsify the mileage reading. There are easier ways of doing it than that. I would be thinking more about the probability of a theft recovery vehicle. I looked at a 94 vert a while back (probably around 96) and it didn't have a passenger airbag.... duh... what's wrong w this picture?
